Rekey Locks after Buying a House in Covina, Before You Unpack

What to know first in Covina

A thorough rekey after a home purchase starts with a walk-through. We count every keyed cylinder: front deadbolt and knob or handleset, garage entry door, back and side doors, keyed patio handles, gates, sheds and the mailbox. Then we look at brands and keyways. Many resale homes in Covina have a mix, say Kwikset on the front and Schlage on the garage door, and those two use different keyways (KW1 and SC1), so they can't share one key as they stand. We can swap the odd cylinder or replace that lock so one key runs the whole house. Kwikset SmartKey locks are rekeyable too; we set them to your new key so the old one no longer turns them. High-security cylinders such as Medeco or Mul-T-Lock may need restricted blanks or authorized service, and we'll tell you if yours fall into that group. Last, we flag hardware that isn't worth rekeying: worn latches, wobbly deadbolts, a bargain lock on the door from the garage. You decide what gets rekeyed and what gets replaced.

How we can help in Covina

• Keying the whole house alike. Kwikset's SmartKey cylinders and its older pinned cylinders both take the same KW1 key blank, so a house with a mix of the two can still share one key. Schlage's standard five-pin SC1 locks behave the same way among themselves. The real obstacle is a lone off-brand or import lock, which we usually replace rather than chase scarce parts for.
• Mailbox lock change. A previous owner's mailbox key is a quiet risk, since mail carries bank statements and new cards. We replace locks on standalone locking mailboxes and on privately owned cluster box compartments so only your keys work. If your cluster box is owned by the postal service, the local post office handles the lock change instead.
• Lock condition check and upgrades. While each cylinder is out, we look at what most buyers can't see: worn pins, loose deadbolt screws, short strike screws, sticky latches and frames that don't line up. You get a straight answer on which locks are fine to rekey and which are worth replacing or upgrading, with a quote for each.
• Key control after the move. Rekeying resets the clock; good key habits keep it reset. We'll cut exactly the number of keys you need, talk through where a spare should live, and set up a simple plan for housekeepers or contractors, such as a keypad code you can delete when the job ends instead of another loose key.
• When the seller's keys don't fit. Damaged and high-security cylinders are the exception. A lock that was drilled, jammed or fitted with a patented keyway may not open cleanly, and occasionally drilling is the honest answer. We'll tell you before doing it, explain the replacement, and still leave every door on your new key before we pack up.

How Covina shapes the job

Family neighborhoods mean school schedules, carpools and a lot of people who may have held the previous owner's keys: babysitters, grandparents, coaches dropping kids off. After you buy in Vincent, rekeying gives you a clean slate before your own kids start getting keys. Many families pair it with a keypad deadbolt so children never carry a key that can be lost at school.

Long commutes shape how you rekey. Many buyers in Covina leave before dawn and get home after dark, so the house sits empty most of the day. We start at 6:30 a.m. every day and work until 11:30 p.m. That makes a before-work or evening rekey realistic. Since the garage entry is often your everyday front door, that lock gets extra attention, and a keypad deadbolt can spare you a lockout at five in the morning.

Inland heat bakes exterior locks. Lubricant dries, pins gum up, and keypads on sun-facing doors wear out faster. When we rekey after a purchase in Covina, we clean and lubricate each cylinder with a dry graphite or PTFE product rather than oil that attracts dust, replace tired springs, and check keypad batteries, which hot weather drains faster than many owners expect.

Example situations

• For example, a couple closes on a 1960s single-story home in Mesa Oaks, and the seller's agent hands over three different keys plus a garage remote. During the walk-through we'd find a Kwikset front deadbolt, a Schlage knob on the garage entry door and a padlock on the side gate. A typical plan: re-pin what matches, swap the odd cylinder, and leave them with one key for every door.
• Suppose you buy a townhome in an HOA community. Your unit's front door and patio gate are yours to rekey, but the pool gate, mailbox units and common doors usually belong to the association. We'd rekey your unit, change your mailbox compartment lock if the HOA allows it, and point you to the management office for pool and gate fobs.
• Consider a bank-owned home off Azusa Avenue bought as a first house. The preservation company changed the locks at foreclosure, likely to a code shared across many properties, and the lockbox was opened by every agent who showed it. In a case like this, rekeying every exterior lock, plus checking for broken latches left over from the vacancy, would be the first job before anything else.
• Suppose escrow closes and the ring from the agent opens the front deadbolt but not the side door or the door from the garage. Maybe a seller swapped those locks years ago and kept the keys in a drawer that left with them. After checking your ID and closing papers, a locksmith would open the two odd locks, read their pins, and bring all three doors onto one new key.

How the visit works

1. Book around your possession date. When you call, have the property address, your possession date and a rough count of exterior doors ready. Photos of each lock face, including the brand stamped on the deadbolt, let us stock the van with the right pins and cylinders. We work every day, 6:30 a.m. to 11:30 p.m.
2. Bring proof of ownership. We verify every buyer before rekeying. A driver's license with your name, matched to the final settlement statement or recorded deed, is ideal. Buying through a trust or LLC? Bring documents showing you're authorized for that entity. It takes a couple of minutes and keeps us from rekeying for the wrong person.
3. Walk the property and count cylinders. We also try every key the sellers left in every lock. That quick test shows which locks the old ring actually operates, turns up doors nobody had a key for, and flags cylinders that were swapped years ago. While walking the perimeter, we keep an eye out for leftover lockboxes and hidden spares so you can remove them.
4. Re-pin each cylinder. Your new combination comes from a fresh code, not a variation on the seller's key. We cut keys on a code machine to the manufacturer's depth and spacing specifications, keeping neighboring cuts within the allowed limits so the key turns smoothly and doesn't wear early. Kwikset SmartKey cylinders are reset with their own tool instead of loose pins.
5. Reset codes and test every key. Then it's your turn. You operate each lock yourself with the new key, enter your keypad codes, and see how the smart lock behaves from the app and from the door. We show you where the batteries go, what the low-battery warning looks like, and where the backup key works, so nothing surprises you later.
6. Hand over the keys and the record. The visit ends with keys in your hand and a clear record of the work. Keep it with your closing papers. It lists the locks we handled and the keying, which makes later additions, like a new smart deadbolt, easy to match. Then reset the garage remotes and you're done.

How we quote the job

• Number of cylinders. The count drives most of the price. A starter condo might have two keyed locks; a larger home with a garage entry, side door, patio handle, gate and shed may have eight or more. A deadbolt and a knob on the same door are two cylinders. We count them with you before quoting.
• Mixed brands and keyways. If every lock is the same brand and keyway, keying them alike is simple. When a house mixes Kwikset KW1 and Schlage SC1, the outliers need a compatible cylinder or a new lock to share your key. That adds parts. We'll show you the most economical way to reach one key, or two if you prefer.
• High-security and smart locks. High-security systems often come with a key card that proves who may order copies. If the sellers handed it over, the cylinders can usually be re-pinned or re-registered through an authorized channel. If the card is gone, replacing those cylinders may be the practical route. Either way, we'll explain the options and their costs before you commit.

What not to do

• Waiting until after moving in. Once your belongings are inside and life gets busy, rekeying slides down the list for weeks or months. Meanwhile, every old key still works. Book it for possession day; it's a short visit compared with everything else you're juggling that week.
• Ignoring codes and electronic access. A rekeyed deadbolt with the seller's keypad code still active, or a smart lock still linked to their app, leaves the door open to them. The same goes for garage remotes and alarm codes. Reset everything programmable on the same day the keys change.
• Tackling a DIY rekey kit on a mix of brands without knowing what you have. Kits are brand-specific, Kwikset SmartKey cylinders need their own tool, and springs lost under a sofa end many weekend projects. A locksmith visit handles every brand at once and leaves each lock tested.

Practical tips before you call

• Keep your closing statement or recorded deed handy for the locksmith visit. Your driver's license still shows your old address, so these documents are what prove the house is yours. A digital copy on your phone usually works and keeps the ownership check to a minute or two.
• Erase the garage door opener's memory using the learn button on the motor unit, then reprogram only your own remotes and car buttons. Change the exterior keypad code too. A seller's old remote clipped to a visor, or a code shared with a landscaper, can open the big door long after the locks are rekeyed.
• Check that the garage entry door and every exterior door has a real deadbolt with a one-inch throw and a strike plate secured by long screws that reach the framing. If a door only has a knob lock, move-in week is a sensible time to add a deadbolt alongside the rekey.
• If you plan a remodel, give contractors a temporary key and plan to rekey once they're finished, or install a keypad lock whose code you can delete. Rekeying twice costs less than wondering how many copies a crew made, and good contractors won't be offended by it.
